Complete newbie to exiftool here, working from windows command prompt.
I've slimmed through the help and couldn't find a way to search by exif tags values.
Specifically, I'm trying to filter out photos that were taken on a iPhone 5 (Model='iPhone 5')
TnX 'n' advance!
Adding -if "$model =~ /iPhone 5/" to the command will process only photos taken with the iPhone 5. Change =~ to !~ to do the inverse (I'm not sure what you meant by "filter out").
